Any recommeded file browser apps that will see wifi devices ?

[Fred98TJ]

I have one of the Seagate 1TB wireless drives. The Seagate app for it is really awkward and clumsy to use.
The standard file browser app that I have (running 4.1.2) does not appear to see a wifi device.
I'm looking for just a standard file browser that will allow me to copy files back and forth from my phone/wireless
drive, etc. There are a zillion in the Play Store.
Anyone have any suggestions.

Thanks,
Fred
